How fast is your car?

Many vehicle owners often wonder, how fast is my car? However, racing on public streets is unsafe. So, I have built an interactive tool based on the MTCARS dataset allowing users to project how fast their car can drive 1/4 mile, virtually.

First Principles

Many vehicle advertisements imply that horsepower equates to speed, and indeed we see a relationship

Model refinement

But power isn’t everything! Here we see that the vehicle’s weight, as well as its power, is related to its speed.

The app takes inputs from the user and uses a model built on MTCARS data to predict the speed.

Using the app!

To explore the app, the user merely has to input 2 input variables:

  • Horsepower
  • Weight

The app then plots and returns the prediction.

Have fun exploring!
